iwlwifi: mvm: Disable uAPSD for a DCM client
A binding object associates virtual MACs to a Phy.
Binding object can ask (and get) air time, thus
allowing several MACs to share the medium.
A binding object can be in either one of 3 states:
1) standalone - A single active MAC
2) Different Channel Mode (DCM) - There are 2 active
MACs or more (not necessarily just clients), but each
has its own channel.
3) Same Channel Mode (SCM) - There are 2 active
MACs or more (not necessarily just clients), that
share the same channel.
This patch introduces an additional condition for enabling uAPSD:
uAPSD should be disabled for a client in DCM.
The reason for that is a low latency issue in Miracast.

The expected throughput table used when estimating a new column
depends on the channel bandwidth. When switching from legacy to

was chosen based on the the channel bandwidth in legacy which is
always 20Mhz. Instead it should be chosen based on the current sta

When enabling MCS9 this bug leads to a problem where the max
expected throughput of the siso or mimo column is 0 as MCS9 isn't

b43: N-PHY: enable forgotten write of hw power adjust table
We've implemented table calculation, but forgot to enable writing it in
power setup function.
By the way document table layout.

b43: N-PHY: fix selection of init & calib values
Logic in specs and our code was wrong. Init and calibration values for
newer cards depend on radio revision, not PHY revision.
To make code clearer, change tables names to include "radio" or "phy".
